cord 11, said pulley 10 being actuated by the general'press driving system.

The rotary plate 5 carri'esa set arranged circumferentially which are designed tc catch the blanks loosely collected at; the: bdttorniY of the hopper by projecting into thee'=holldw cf; the cupped blanks and to bring them to a channel guide 13 whose opening is flared andis positioned. tangential to the. circumference, of. thea-aes ofthe lingers 142.

'A flexible blade 1.4V (Fi'g.4)" is securedl upon thevhopper wall, it is directedinwardls and shaped so as to push back to the bottom ofthe hopper. the blanks whichv have not' been caught b'ut'wouldL reachY the channel opening as Well as those thaty would eventually cap a blank previously caught.

It will be. noted that owing tothe existence of the conical/hopper wall la no wed'ging effectcan take4 place. in the lower party-ofi said hopper between the loose blanks and",` vthose already caught on the. ngers: 1'2, the former. obviously will be causedv to slide up' the incline of' said fwall la.

Theopening of the channel 13` is suitably; flared vat 13b and its bottom which iscut out and rises Vgradually is provided' with two spring blades,r 15 oneach side of' a groove'lf'havingsuflicient depth to' allow the passage and theV withdrawal upwards' along said. guide which is partially cov ered. along' its whole length by a' cover. 13a'.V

The blanks as' they moveY along; in the channel push those in front' further. on,.the impetus being, given every time by the'niewlyY presented" blankK which' is. being. pushed" in the opening by its fingerrr It will hereinafter' be seen that thel outlet endl :of the channelisperiodically. closed and" consequently as. the' rotaryfp'late 5"rot'ates permanently the blanks mighttbe crushed inthe'channel.

At the top o-f arm 23 is mounted a plate 27 operating as a pressure plate for the cupped blank and whichzsenvesfto: press the blank on the punching die when the arm 23, containing the blank, is lowered over` the vsaid die.

Thev arm carrying shaft 24i is provided with grooves v at' its lower end (Fig. 2) where it carries a-cranls pin 28n which is provided with corresponding projections and is designed to rotate said shaftf. The shaft 24 is guided in a frame 29.

take place substantially at the sameftime. butU 5 with apslight'V advance. of the horizontal rotary movement, to break the connection betweenthe..

low of some'of them and take them along to.-

As they come `upon the spring blade 16 at the'channel inlet, they move' up the incline so that the fingers draw. back and ofwards the channel 13.

andunder the slot of said spring blade the bottom. y

The blanks pile up in the channel and those in excess .come out through opening 17 and return to the hopper. v l Y The foremost blank, that is the one at the` end of the slide 19 is stopped by the obturating' sliding device 21. f v Y When the oscillating arm 23 comes opposite the guide and pushes back the obturating sliding device 21, a blank is drawn by suction and stcks to said arm. At that instant the cam 41 rotatesy the crank pin 28consequently also the arm.:23

:from left to right, which latter brings the blank above the punch. As the cam 49 now allowsfthe downward movement of the roller 48, the spring 50 returns both shafts 24S- 24ifdownwards and thereby lowers the arml 23 which owing-to the support given by its cover 27 places the 'blank on thepunch head.

The action of the cam necting rod'system inthe opposite direction and the crank pin 28 ls rotated backwards drawing the arm 23 towards the'channel. Simultaneously to this displacement and with a slight delay at the origin, so that the blank remains in engagement with the punch without risking of being drawn away by the suction effect, the double shaft 24S- 24i is moved upwards by the cam 49, so that the apparatus which has been described and illustrated is by no means limitative and that the various movements may be produced by any known equivalent mechanical devices.

- It will also be understood that the invention 'comprises Various applications and that according to the blank and to the stage of punching there may be obtained by changing the guides and the carrier arm a set of devices which will feed a series of machines.

Lastly, the invention may be applied to presses of all kinds and to machine tools in which the blank is brought to the capped position.
